Loom

External memory for agents

AI-native coordination layer. Multi-agent task routing, checkpointing, and crash recovery for AI coding assistants.

npm install @createsomething/loom-mcp

The Problem

AI agents forget everything between sessions. Context windows have limits. Conversations get summarized. Work gets lost.

The Solution

Loom provides external memory for agents.

  • Session checkpointing — Save progress, resume from any point
  • Crash recovery — Session died? Pick up exactly where you left off
  • Smart routing — Route tasks to the best/cheapest/fastest agent
  • Multi-agent coordination — Multiple agents, one task queue

MCP Apps (Interactive UIs)

Loom supports the MCP Apps extension for interactive task visualization. When you call task visibility tools, supported clients render an interactive Kanban-style task board:

  • One-click claim, complete, or release tasks
  • Real-time status updates
  • Filter by status, label, or agent

Supported Clients: Claude.ai, VS Code (Insiders), ChatGPT, Goose
